Dealing with comfort disruption

Operating mode "Add. heat only"

In the event of malfunctions that cause a low indoor temper-

270, which means that heating only occurs with the immer-
sion heater.
Activate the mode by holding in the operating mode button
for 7 seconds.
Note that this is only a temporary solution, as heating with
the immersion heater does not make any savings.
